Incompressibility of neutron - rich matter

The saturation properties of neutron-rich matter are investigated in a relativistic mean-field formalism using two accurately calibrated models: NL3 and FSUGold. The saturation properties—density, binding energy per nucleon, and incompressibility coefficient—are calculated as a function of the neutron-proton asymmetry α ≡ (N − Z)/A to all orders in α. Good agreement (at the 10% level or better)...

Hyperon-rich matter in neutron stars.

We study the equation of state of hyperon-rich matter for neutron stars using an extended relativistic mean-field model. We take special care of the recently proposed non-linear behaviour of the vector field which gives a much better description of Dirac-Brückner calculations. The hyperon-hyperon interaction is also implemented by introducing additional meson exchanges. These new terms avoid th...

Isospin-rich nuclei in neutron star matter

Stability of nuclei beyond the drip lines in the presence of an enveloping gas of nucleons and electrons, as prevailing in the inner crust of a neutron star, is studied in the temperature-dependent Thomas-Fermi framework. A limiting asymmetry in the isospin space beyond which nuclei cannot exist emerges from the calculations. The ambient conditions like temperature, baryon density and neutrino ...

Neutron rich matter, neutron stars, and their crusts

Neutron rich matter is at the heart of many fundamental questions in Nuclear Physics and Astrophysics. What are the high density phases of QCD? Where did the chemical elements come from? What is the structure of many compact and energetic objects in the heavens, and what determines their electromagnetic, neutrino, and gravitational-wave radiations? Moreover, neutron rich matter is being studied...

Constraining the neutron-proton effective mass splitting in neutron-rich matter

One of the most fundamental properties characterizing the propagation of a nucleon in nuclear medium is its effective mass[1, 2, 3]. The latter describes to leading order the effects related to the non-locality of the underlying nuclear effective interactions and the Pauli exchange effects in many-fermion systems. In neutron-rich matter, an interesting new question arises as to whether the effe...
